Accidental or remote starting can
cause severe personal injury or death. Before
removing a panel or access door, disconnect
the negative (−) cable at the battery to prevent
the engine from starting.
Either a Digital Display or a control switch is
mounted on the control panel (Figure 2-1). See
DIGITAL DISPLAY (p. 2-3) regarding function. Up
to three Digital Displays may be connected in the
control system. See Page A-3 for connections.
CONTROL SWITCH (S4)
The control switch, when located on the genset, is
mounted on the control panel (Figure 2-1). Unsnap
the connector for access to its terminals (Fig-
ure 5-3). Replace the switch if Start does not close
terminals 2 and 3, Stop does not close terminals 1
and 2, Green does not light when battery voltage is
applied across terminals 7 (−) and 8 (+), or Amber
when battery voltage is applied to terminals 7 (−)
and 6 (+).
EMERGENCY STOP SWITCH (CB1)
The switch/circuit breaker is mounted on the control
panel (Figure 2-1). Disconnect the leads and check
electrical continuity across the two terminals. Re-

ON and OFF. For easier access to the switch termi-
nals, push out the four plastic buttons that secure
the panel and pull the panel and switch forward.
DC CIRCUIT BREAKER (CB2)
